The XEL-1 is the world's first organic light-emitting diode (OLED) television, designed by Sony in 2007 and produced for sale the following year. It was also the world's thinnest television during its production, at 3 mm. It has a screen size of 11 inches with a native resolution 960×540. The top of the base has 2 speakers and the power, volume, channel, input, and menu buttons, which are backlit, so the symbols and abbreviations change when the XMB interface is accessed. The back of the panel has a DMeX service input, a 16-volt DC input, a VHF/UHF/cable input, a Memory Stick slot, and two HDMI inputs. On the left side of the panel there is an analog/digital audio output.
The XEL-1 has a contrast ratio of 1,000,000:1, high color saturation, large viewing angles, high screen uniformity, and low power consumption.[1] On the other hand, it has poor primary color accuracy, a quarter of the full HD resolution (1920×1080), no anti-judder processing, a light-reflective screen, few inputs, a non-detachable panel, a small screen and a MSRP of US$2,499.99.[2][1] It was sold in the United States, Canada, Russia, Japan, Europe and Australia. Years later in 2017, Sony officially sold their first OLED TV in market, the BRAVIA OLED A1/A1E with 4K HDR.
